Application filed February 6, 1928. Serial No. 252,095.

The invention forming the subject matter of this application relates to wmdow ventilators.

The primary object of the inventlon is the provision of a Window yentilator frame of animproved construction, which may be readily secured to a window frame and which securely supports a deflector in such a manner as to obviate any possibilities of noise and rattle incident to air impact.

Another object of the invention is to provide a window ventilator frame which is highly useful and simple in construction. Convenience of arrangement, lightness and comparative inexpense of manufacture are further objects which have been borne in mind in the production and development of the invention. lVith the above and other objects in view my invention resides in the combination and arrangements of parts hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention hereinafter disclosed may be made within the scope of the appended claims, without departing from the spirit of the in vent-ion.

The invention is clearly illustrated in the accompanying drawings, in which Figure 1 is afront view of the device showing the same attached to a window frame,

Figure 2 is a cross sectional view of the windowventilator deflector as attached to a window frame, the section being taken along the line 22 of Figure 1, and shown on an enlarged scale, and

Figure 3 is a sectional plan view of my device taken on the line 3-3 of Figure 2.

Itcferring to the accompanying drawing wherein similar reference characters designate similar parts throughout, the Various figures described above adequately illustrate my invention, and the following detailed description is commensurate with the above mentioned drawing in enabling an artisan to construct and assemble the constituent parts of the same.

In carrying out my invention, I make use of end plates designated by the numeral 5, said end plates having angularly disposed deflector supports 6 thereon. The, deflector supports 6 are integral parts ofthe end plates 5 and are bent at right angles thereto. Tongues 7, preferably of. rectangular shape, are bent out of the end plates 5 in such a manner that one side of the rectangular tongue remains integral with the end plates 5 while the outer edge of the tongue is bent away from said end plates into a position opposite to and in parallelism with the angularly disposed deflector support 6. Al-

though in the illustration three tongues 7 are shown on each end plate 5, the number of tongues may vary in accordance with practlcal requirements.

A deflector plate 8 1s adapted to be slipped between the deflector support 6 and the. tongues 7 so that the ends of the deflector plate rest upon the angularly disposed sup ports 6;

The deflector plate 8 is provided with tongues 9 punched out of the deflector adj acent to and spaced from the end thereof, sothat when the deflector is disposed upon the supports 6 the tongues 9 are in registry with the tongues 7 on the endplates 5. The

tongues 9 are preferably rectangular, one side thereof being integral with the deflector 8..

a manner as to resiliently press against the v bent end of the prongs 7, when the ventilator is assembled.

Before the ventilator is The free end of each' tongue 9 is 3 bent out of the plane of the deflector in such assembled, the end H plate may be inserted between a window w casement 11 and the window stop 12 as it is. clearly shown in Figure 1. The end plates 5 are provided witha hole 13 permitting the insertion of a screw 14 therethrough which screw extends through the window stop 12 and into the window casement 11, thus -se-.

curing the endplatcs in place. After the end plates are firmly secured to the window casement the deflector 9 is inserted in place so that the ends thereof rest against the defiector support 6 while the tongues 9 thereof are brought in registry with the tongues 7 Ton the respective end plate. During the assembly a certain amount of force is required to slide the tongues 9 below the tongues 7 so that the frictional engagement between the complementary tongues firmly holds the defiector in place thereby obviating any possibility of noise or rattle due to the impact of air.

Although deflector is shown with tongues 9 thereon for the engagement of the complementary tongues 7 on the plates 5, it is to be noted,that any standard deflector such as a glass plate, wood or metal plate could be inserted between the deflector support 6 and the tongues 7. considerable Va iation as to the thickness of the deflector is permitted because of the fact the spacing between the deflector support and the bent ends of the ton ues 7 maybe readily adjusted by simply bonding the tongues 7 so as to change the angular position thereof. The tongues 7 must be so bent that the space between thewends thereof and the deflector support 6 is slightly smaller than the thickness of tli dflGCtOlkSQ that the deflector is held -firmly in placeby the resilient-pressure exerted thereon by the metal tongues 7.

It is also to be noted that the tongues V be of any desirable shape, such as triangular or polygonal, long as they present an out- I resi ient" ressure uuon a dei prevent any side edge'or point which is adapted to short lector plate with without complementai'y tongues thereon, thereby resili ntly pressing the same against the deflector support 6, thus holding the same in position wi h sufiicient firmness to ibration tl'iereo'i'.

In manufacturing the device while the various elements thereof be constructed in any suitable manner and of any suitable material, yet it is preferable to form thel same from sheet metal stampings on account of the cheapness, lightness and strength or" the latter; but irrespective oi these features in manufacturing" the GSSQDt-lill features of 4 the invention are always preserved.

Having thus described my invention, what I now claim as no-veland desire to secure by 2 Letters Patent is 1; In v a window ventilator, two end brackets adapted to be secured to a window, an angulariy positioned deflector support on each bracket, tongues extending from said end brackets toward said deflector supports, a deflector plate disposed on said supports, and means on-t-he'ends of the deflector plate to cooperate with said tongues for pressing the ends of the deflector plate against said support.

2. Ina Window ventilator, two end brackets adapted to be'secured'to a window, an

angularly positioned deflector support on each bracket, tongues bent out of said bracket andrcxtending opposite said support; a deflector plate frictionally secured between said sue )orts and said ton ues an cured between said supports and\ said tongues, an edge of each bracket being adapted to be inserted between a window stop and a window caslng; and means extending thru the window stop and thru the bracket into the window casing for securing the bracket in place." 1 1 4. In a window ventilator, two end brack ets adapted to be secured to a window; an angularly positioned deflector support on each bracket; tongues bent out of said bracket and extendingflopposite said support; a deflector plate, tongues on said do fleet-or plate being complementary to said bracket tongues, said deflector held in pcsltion by the pressure or said complementa'ry tongues upon each other.

5. In a window ventilator, two end brackets adapted to be secured to a window; angularly positioned deflectorsupport form- 'ing an integral part of each bracket; re-

silient tongues integral with said brackets,

the free end of said tongues being disposed opposite said support; a deflector plate restlng'upon said supports, resilient tongues integral with said deflector plate and being complementary to said bracket tongues, said 7 deflector being trictionally held in place'by the engagement ofthe free end of the complementary tongues.-

In testimony whereof I aflix my signature.
